From precision machining to advanced microscopy, the demand for higher-power, ultrafast lasers continues to grow. Traditionally, researchers have relied on single-mode fibers to build these lasers, ...

A new optical device allows researchers to generate and switch between two stable, donut-shaped light patterns called ...

Smart lighting has quickly moved from a niche home-tech upgrade to an essential feature of modern living. As connected devices, energy-efficient systems, and automation become commonplace, lighting ...

Scientists have generated ultra-stable, donut-shaped light structures called skyrmions. These innovative beams can carry data ...

Researchers have built a paper-thin chip that converts infrared light into visible light and directs it precisely, all without mechanical motion. The design overcomes a long-standing efficiency-versus ...

Light Emitting Diodes (LEDs) are fast becoming the most popular lighting option. Industry forecasts anticipate the market will continue to expand at an annual rate of 20% from 2011 to 2016, with the ...

The latest Windows 11 Insider Preview Dev Channel build introduces some updates to the address bar and home page for File Explorer and the rollout of Unicode Emoji 15 (with new symbols for wireless ...

This article will continue the discussion of power quality in lighting and look at some of the ways to control harmonic content. There are several standards in use and the categorization of emissions ...

If you primarily game on PC, there’s a good chance you own more than one component with RGB lighting. You may have even made the mistake of buying RGB parts from different manufacturers. If you just ...

The phase and the group velocity of light propagating in conventional optical media cannot exceed the speed of light in vacuum. However, in so-called epsilon-near-zero (ENZ) materials, light exhibits ...
